6. System
Verification
When the hardware installation is completed, double-checking the installation is
recommended to make sure that the installation was completed properly so that the
subsequent software installation and system debugging can be implemented successfully.
The checkup involves the following three steps:
•
Making an overall inspection
•
Checking system power supply
•
Checking board status after power-on
6.1. Overall
Inspection
The overall inspection refers to a review of the entire installation. The check must cover
the cable distribution, connectors, and sockets.
6.1.1.
Checking the Cable Distribution
¾
Check the power cables and grounding wires
1. Ensure all the power cables and grounding wires are reliably and correctly
connected.
¾
Check the intra-module cables
1. Ensure all cables are connected correctly and firmly connected.
2. Ensure all cables are bundled properly and the spacing between cable ties is
appropriate.
3. Ensure the cable ties are not overlaid, and have no sharp ends.
¾
Check cables and optical fibers
1. Ensure the cables are not stretched too tightly at turn points.
2. Ensure the wiring route is correct and cables are bundled with the same intervals.
3. Ensure the cables inside the rack are straight and smooth without crossover and
that the cables outside the rack are bundled together.
4. Ensure the cables in the guide rails are neatly arranged. All cables are bound
properly without damage to the insulation.
5. Ensure that proper surplus for the cables are reserved. Make sure the cable ties
are cut with flush ends and without superimposition.
¾
Checking Connectors and Sockets
1. Ensure all the sockets are in good condition without broken or bent pins.
6.1.2. Power
Supply
¾
To check the power supply
1. Unplug the cards from the backplane (the cards may remain in their slots, but they
must not contact the backplane).
2. Use a multimeter to check whether the input -48/60V DC power supply is within
range.
